概要
- 論文の詳細を見る
Photocyclization reactions (γ=254nm) of γ-methyl δ-(4-hydroxybutyl) and δ-(-4-hydroxypentyl) α, β-unsaturated γ, δ-epoxy nitriles gave spiroketals and spirothers diastereoselectively, whereas reaction of δ-(6-hydroxyhexyl) nitrile allorded no cyclization product. In addition, photocyclization of nitrile bearing a carboxyl group in the δ-side-chain afforded spirolactone.
